You are creating a Grid/Non-Grid kVp variable abdominal technique chart. You have selected a sample patient that has an abdominal measurement of 7 cm. Based on your machine’s mA settings and your patient’s weight, you chose your top three mAs settings and created three test radiographs. You selected the radiograph produced using 250 mA at 1/40 seconds = 6.25 mAs. Your machine has a grid ratio of 12:1. Given this information, calculate your kVp and mAs for a patient measuring 11 cm. You are NOT required to show your work to receive full credit.
